Neil deGrasse Tyson: Galactic Flip-Flopper on Pluto?


Astrophysicist Neil deGrasse Tyson spoke at The Commonwealth Club of California in San Francisco last night. Following his very entertaining and enlightening discussion of the debate he himself sparked over whether Pluto should be classified as a planet, Tyson was asked by moderator Brian Hackney about a previous book of Tyson's in which he seemed to take the opposite view of Pluto, a view that would have saved him a lot of hate mail from third-graders.
This was a return engagement by Tyson at The Commonwealth Club. As always, he was brilliant, funny, friendly.
